It does it even in the front of the wheels on the front. The clearance between the tire and build up about 3/4 of an inch. I noticed even in the rear wells the build up is there, but not quite as bad. It seams like the wheel wells are the cause, because the wells are not a smooth plastic but a felt like material. I did add the rear wheel well liners.
I've noticed that on this 2020 RST All Star Edition Silverado, that the snow builds up rather quickly in the wheel wells. To a point the when you turn the wheel it sounds like it's going to bend the lower fender and damage them. With my old truck 2010 Sierra I didn't have this problem. Anyone else notice this on the newer style? Any fixes for this???? Other then knocking the build up off every time I park the truck. Thanks in advance Bill
